Thinly sliced beets will shrivel when roasted in the oven and become crisp delectable veggie chips. Serve them to guests as dried out bloody bat ears and they’ll lick their lips with eerie satisfaction! To make, pre-heat the oven to 350 degrees. Slice beets very thinly, using a mandolin if you have one. Drizzle some olive oil on a baking sheet and spread around evenly. Place sliced beets on the greased baking sheet and brush with a bit more olive oil. Sprinkle generously with salt and bake for 20 – 30 minutes. Remove from the oven and they will crisp as they cool.
